Problems solved by technology

At present, in production, one is to block the filtration of the breeding water body, which not only has high production costs, but also does not meet the requirements of large-scale cultivation of seedlings for a large amount of water;
Pesticides such as trichlorfon and pyrethroids are often used to kill Daphnia mammoth in seawater seedling pools. These pesticides not only cause poisoning to farmed abalone, sea cucumber, shrimp, crab, etc., but also cause serious pollution to the water environment. Threat to human food safety

Abstract

The invention discloses a Harpacticoida killing agent. The killing agent comprises 30wt% of a Radix Polygalae extract effective component presenegenin with the content of 90% or more, 16wt% of a dispersant, 24wt% of a wetting agent and 30wt% of a carrier, the dispersant is Morwet D-400, the wetting agent is Morwet EFW, and the carrier is diatomite. The Harpacticoida killing agent has the advantages of simple and convenient operation, low toxicity to farmed animals, and one-time thorough killing of Harpacticoida.

Description

technical field [0001] The invention relates to a killing agent for fleas, in particular to a killing agent for Daphnia mammoth. Background technique [0002] Daphnia is a general term for some species of crustacea Daphnia (Harpacticoida), which is the dominant group in marine meiofauna. In the production of abalone, sea cucumber, shrimp and crab seedlings, some species multiply in large numbers, which brings serious predators to the early production of seedlings. One is that Daphnia mammoth overgrows in the water body, which not only consumes a lot of oxygen, resulting in hypoxia in the water body, but also competes with the cultured abalone seedlings and ginseng seedlings for bait. At the same time, due to the lack of unicellular algae, ammonia nitrogen cannot be used, resulting in poisoning of the cultured seedlings The 2nd, Daphnia mammoth breeds in a large number, all bite damage to abalone seedlings, ginseng seedlings, molted shrimp and crab seedlings, causing a large...
